Firstly, according to the relative atomic mass ratio of elements

That is 2 * (2 *1): 2 *16: 2 * (2+16) =1:8: 9.

Second, the chemical formula you wrote is wrong. Mainly because the chemical formula must always conform to the conservation of charge and matter. If this equation holds, then the left side of the same element should be equal to the right side.

As far as this formula is concerned, there should be five C's on the left and five C's on the right.
